The composition of apple base wine was found to be suitable for conversion into vermouth. The spices extract contained more TSS, tannins, esters, volatile acid but lower titrable acid than apple base wine. To optimize and develop apple vermouth with different ethanol concentrations (12%, 15%, 18%), sugar content (4%, 8%) and spices extract (2.5% and 5.0%) was prepared and was evaluated. Significant differences in physico-chemical characteristics and sensory quality amongst the vermouths having different levels of alcohol, sugar and spices extract were noted. Generally, increasing ethanol content decreased titrable acidity, tannins, macroelements and colour units while micro-elements, viscosity and total esters were increased. Increased sugar level affected TSS, apparent viscosity, pH, esters, free aldehyde, total sugar, K, Cu and Mn contents. Level of spices extract (2.5 & 5.0) did not effect TSS (ºB), titrable acidity, colour, total sugar, total tannins, volatile acidity, increased mineral contents except for K, esters and aldehyde contents. Increase in alcohol content upto 15% increased the sensory score of the product. Increased quantity of spices extract, however, decreased the mean sensory quality of vermouth. However, sensory scores for 4 or 8% sugar and 2.5 or, 5.0% spices extracted were similar. A product with 15% alcohol, 4% sugar and 2.5% spices extract was preferred the most in overall sensory quality. The studies revealed that apple fruit is suitable for making vermouth by the method described. The spices, herbs, their parts and the quantities used are also reported.

The research was carried out to ascertain the feasibility of preparing paneer from milk blend containing low pressure homogenized milk to avail the benefits rendered by homogenization. Standardized milk was subjected to two-stage homogenization (4.90 and 0.98 MPa respectively) and then blended with unhomogenized standardized milk in three proportions (i.e. 3:7, 4:6 and 1:1, w/w). It was necessary to add calcium chloride to the milk blend to improve the firmness of resultant paneer. The experimental paneer samples obtained from ‘milk blend’ containing homogenized milk, as well as control sample (only from unhomogenized milk) were studied for their proximate composition, physico-chemical characteristics, textural properties and sensory quality. Paneer obtained from milk blend (homogenized:unhomogenized; 4:6 w/w) resulted in greater fat recovery and moisture content culminating in significantly higher yield compared to control paneer (CP). The hardness of paneer obtained from blended milks was lower, but the springiness of BMP3:7 sample was greater than that of CP. The total sensory score of experimental paneer BMP4:6 was similar to the score associated with CP, but greater than the scores associated with paneer samples BMP3:7 and BMP1:1. Blending of homogenized (low pressure) milk with unhomogenized milk in 4:6 proportion helped in obtaining paneer with superior fat recovery and yield compared to use of unhomogenized milk, without any adverse effect on sensory properties and with concomitant cost savings.

Sel-roti is a deep-fat fried, puffed, circular spongy doughnut like indigenous,non- alcoholic fermented cereal product of Nepal. A study was conducted to study the effect of batter ageing on physiochemical and microbial changes and its impact on sensory quality of Sel-roti.Ten samples of batters were aged for 9 h at 3 h interval at temperatures30°C, 40°C and 50°C.After ageing, acidity as lactic acid, reducing sugar and total sugar contents of the batter had increased significantly (P<0.05). The total sugar content of the batter started to decrease after 6 h of ageing. During the ageing period of 3 hour bulk density of products were decreased significantly (p<0.05) for all temperatures of ageing but after 3 hours of ageing it was increased slightly for 40°C. Fat uptake of sel-rotifound to decrease as ageing proceeds. Lactic acid bacteria, yeasts and mold co-existed in sel-rotibatter. LAB and yeast count at the end of 9 hour of aging was higher at 30°C than at 40°C. LAB and yeast count at 50°C was markedly decreased during 9 hour of ageing of batter. Mold count in the samples of batter during aging was decreased at all temperatures. Among study time and temperature of ageing quality of sel-roti prepared from batter aged at 30°C for 6 hour was found to be good in terms of sensory quality and cost effectiveness.  DOI: http://dx.doi.org/10.3126/jfstn.v8i0.11721 J.

Physical And Chemical

The physical and chemical characteristics of the fruit have immense significance as they ultimately affect the quality of processed productsprepared from them. Over ripening of Sapota (Manilkara zapota) fruits at the post-harvest stage usually results in dramatic decline in quality.In the present study, physico chemical analysis (which includes Weight loss, Colour, Texture, TSS, pH, TA and Ascorbic acid content) ofedible Aloe vera gel coated Sapota fruits packed in LDPE and stored at 15 ± 2? were studied at regular intervals of 5 days i.e., 0th,5th, 10th,15thand 20th days. The dip treatment of Aloe vera gel coating 1:2, 7 minutes had best retained the physico chemical characteristics than the othertreatments performed and was found to be the most effective treatment in maintaining the fruit quality attributes along with the shelf lifeextension of about 20 days.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11703 Int J Appl Sci Biotechnol, Vol. 3(1): 20-25

The Difference

The effect of raw material characteristics (longissimus dorsi and biceps femoris) on dry-cured loin and ham quality from three different Iberian · Duroc genotypes was studied: GEN1: ♂ Iberian · ♀ Duroc1, GEN2: ♂ Duroc1 · ♀ Iberian; GEN3: ♂ Duroc2 · ♀ Iberian. GEN1 and GEN2 are reciprocal crosses, while the difference between GEN2 and GEN3 is the Duroc sire line. The line Duroc1 (DU1) was selected for the manufacture of dry-cured meat products, whereas the line Duroc2 (DU2) was selected for meat production with low carcass fat. Raw material and dry-cured meat products did not differ between reciprocal crosses (GEN1 vs. GEN2). However, the genotype of the Duroc sire line affected the quality of meat and dry-cured meat products. GEN1 and GEN2 had higher adipogenic nature and higher postmortem pH than GEN3, and as a result, these dry-cured meat products had better instrumental and sensory quality than those from GEN3. By contrast, meat from GEN3 had lower pH, fat content, and oxidative stability which decreased the quality of dry-cured meat products. Therefore, there was a close connection between raw material and dry-cured meat products quality as it was affected by characteristics related to the genotype such as the adipogenic character and meat quality traits associated with pH.

Gandaria plant grows with tree habitus with a height of up to 27 m Spread of gandaria plants in Maluku, generally on Ambon Island and Saparua on Ambon Island, gandaria plants are spread from the coast to the hills. This study aims to determine the quality of sugar content, total acid, pH, water content and production of gandaria fruit (Bouea macrophylla Griff) in different geographical conditions on the island of Ambon using a purposive sampling method and laboratory analysis. The results showed that at an altitude of 0-400 asl with a production of 654 kg, 400-700 asl with a production of 681 kg and an altitude of 700-1100 asl producing 925 kg and the height of the place also affected the quality of gandaria with an average total sugar of 12.69%, content water 80.18%, acidity level 6.81% and pH 3. It was concluded that the higher the altitude of the place will affect the production and quality of gandaria fruit (Bouea macrophylla Griff).
